Surely this is the nub of this whole thread? What A might consider a well protected, friendly path on their ascent, B may have had a totally different experience. Il Duce has been quoted as a good example of a lonely route. Virtually everyone I know, including myself, who has climbed it would agree, with the obvious exception of jcm. The same is true of many of the routes at places like Blackchurch, Exmansworthy or Carn Gowla. Loneliness is a state of mind.
Anyway here's a few personal examples from a long and often inglorious climbing career.
Limpet Slab, Halldrine: my first lead, aged 7. Stopped halfway up, no runners of course, and looked down at my grandfather, the waves licking his feet. Definitely a lonely feeling!
Devil's Slide: an early (3rd/4th?) ascent in the 60s. No runners again, damp lichen, skiddy klets, same second, same feeling.
Right Angle FA: Felt very alone leaving the stance on the last pitch. Second, a non-swimming, sandstone-loving Londoner, not happy and extreme(!) climbing to come or so I thought.
America via the original sea level entry. For me a top 10 lonely lead.
Terminal Trajectory, Wharton Main: death on a stick - we die alone!
Andromeda Strain FA: seconded this, but with no-one else around, a crap belay and Pat 80ft above with a solitary rattling wire suggesting I watch the rope, very lonely.
Any of the routes in Deep Zawn on Lundy, when you and your partner are the only climbers on the island.
